Compact Shield Aluminium Alloy Enclosure High Frequency Rogowski Coil Integrator Current Converter

HF High Frequency integrator       HF is a High Frequency Rogowski coil integrator, in a compact shield aluminium alloy enclosure, powered directly from the mains.It is providing the measurement of all kinds of waveforms like 3/5μs, 8/20μs,10/350μs,frequencyfrom 100kHz to 1MHz, it also features in direct connection to oscilloscopeWhat does Integrator do?• Rogowski coil output is weak voltage mV signal,HF has ability to amplify and convert it to standard signal which could be catched by multimeter and scope.• Rogowski coil output is proportional tothe frequency of the measured current, the signalequalization ensure a linear response on a widefrequency range. TP allows to use coils on differentelectrical network frequencies, keeping the sameoutput level over the frequencies.•An integrator is essential to equalize and shift by 90° the output signal from the Rogowski coils. It consists of an activeelectronic circuit with negligible offset and a good linearity.FeatureTP can be combined with any model and size of Y-FCT or FCT Rogowski coils.The available values are: 0-12V peakOn request the input value can be customized according to the application.TP and Rogowski coil is a very flexible system, suitable for high power load analysis, impulsivecurrent monitoring, DC ripple measurement, etc.Due to its specific features, flexible Rogowski coil is an extremely comfortable solution for current measurement and can be used in a number of cases where traditional current transducer is not the adequate solution.Advantage• High read accuracy 2%  • Wide power supply arrange:4-12VDC• 1/5μs,8/20μs,10/350μs waveform restore•Up to 500kA lightning current measurementRelated ProductsH-FCT   ApplicationsMeasuring devices, lab instrumentation•Lightning protection• Lightning monitoring•Lightning current measurement• Pulse waveform analysis  What is a Rogowski coil?Rogowski coils have been used for the detection and measurement of electric currents for decades. They are based on a simpleprinciple: an "air-cored" coil is placed around the conductor in a toroidal fashion and the magnetic field produced by the current induces a voltage in the coil. The voltage output is proportional to the rate of change of current. This voltage is integrated, thus producing anoutput proportional to the current.By using precision winding techniques, especially developed for the purpose, the coils are manufactured so that their output is notinfluenced by the position of the conductor within the toroid, and to reject interference from external magnetic fields caused, for example, from nearby conductors.Basically, a Rogowski coil current measuring system consists of a combination of a coil and conditioning electronics.Rogowski coil current transducers are used for the AC measurement.They can be used in similar circumstances to current transformers but for many applications they have considerable advantages:• Wide dynamic range.• High linearity.• Very useful with large size or awkward shaped conductors or in places with limited access. Thanks to the structure without hardcore, the coil can       be easily manufactured according to the application or to the available space.• Unlike traditional current transducers, there is no danger from open-circuited secondaries.• They cannot be damaged by large overloads.• They are non-intrusive. They draw no power from the main circuit carrying the current to be measured.• They are also light weighted and in some applications are light enough to be suspended on the conductor being measured.The transducer does not measure direct currents but, unlike a current transformer, it can carry out accurate measurements of ACcomponent even if there is a large superimposed DC component, since there is no iron core causing saturation. This feature isparticularly useful for measuring ripple currents for example in battery charging systems.Specification  ModelHFRated output1V AC peakMaximum Output(overload)12V AC peak    Rated ratio1kA/1V10kA/1V50kA/1VMinimum ratio:1000A/1VRead Accuracy2% typical at 10% to 1000% of rated Current @25ºCPhase error≤0.5°Linearity±0.5% of reading(10% to 1000% of range)Minimum Current measurement10% of rated ratioTypical waveform 1/5μs,8/20μs,10/350μsResponse time≤1usPower consumption300mWOutput on 0A    (zero drift)≤10mVTemperature drift200ppm/ºCWeight160gDimension86*90*29mmPower supply4-12V DC (included 85-265AC to 12V DC adaptor)Operating temperature-20ºC to 70ºCStorage temperature-30ºC to 90ºCRelative humidity80% max.without condensationProtection degreeIP20Terminal(Locks type)     Input:locked with H-FCT signal cableOutput:BNC female terminal with 2m BNC male terminal cable     Power:DC-DC terminal 5.5*2.0mm² with 85-265VAC adaptor Other requirements, please contact us to OEM.Actual waveform showTest Equipment:                                                    8/20 test waveform                                                         Transient current waveform
